Highly Photoluminescent Blue Ionic Platinum-Based Emitters.

New cycloplatinated -heterocyclic carbene (NHC) compounds with chelate diphosphines (P^P) as ancillary ligands: [Pt(R-C^C*)(P^P)]PF (R = H, P^P = dppm (), dppe (), dppbz (); R = CN, P^P = dppm (), dppe (), dppbz ()) have been prepared from the corresponding starting material [{Pt(R-C^C*)(μ-Cl)}] (R = H, A, R = CN, B) and fully characterized. The new compound has been prepared by a stepwise protocol. The photophysical properties of - and - have been widely studied and supported by the time-dependent-density functional theory.

Manufacturing Te/PEDOT Films for Thermoelectric Applications.

In this work, flexible Te films have been synthesized by electrochemical deposition using PEDOT [poly(3,4-ethylenedioxythiophene)] nanofilms as working electrodes. The Te electrodeposition time was varied to find the best thermoelectric properties of the Te/PEDOT double layers. To show the high quality of the Te films grown on PEDOT, the samples were analyzed by Raman spectroscopy, showing the three Raman active modes of Te: E, A, and E.
